Application filed May 2, 1921.

This invention relates to compressed air mechanism for motor cars andthe like.

In the improved mechanism the air compressing cylinders are of equalsize and are inclined to one another, the pistons of the cylinders beingactuated by a crank shaft driven by means of a Worm Wheel and a Wormconnected to the motor shaft of ther car by means of an elastic joint;the said cylinders communicate with a chamber in which is a movablepiston submittedv to the action of a spring and operating to obturatethe air admission ports to the cylinders when the air pressure reaches acertain value.

The annexeddrawings illustrate the 1nvention.

Figure 1 is a longitudinal vertical section of the apparatustaken online X-X of Fig. 2.

Fig. 2 is a cross section on line Y-Y of Fig. 1.

The apparatus is composed of a compressor body 2 having inclinedcylinders 7, 71. 'Ihe rods 6 of the pistons 8 and 9 are coupled to twocranks 5 keyed at 18()o to one another on the shaft 3.

The mov-ement of the motor of the car is transmitted to the shaft 3through a worm Wheel 10 arranged between the tivo connecting rods 6,which gears with a Worm 11 mounted on ball bearings 12, 13 and directlyvdriven by the motor of the car through an elastic joint 14. Thecylinders 7 71 are surrounded by a Water circulation jacket 15.

The admission of the air into the cylinders 7, 71 is eifected throughports 16, 17 uncovered when the pistons 8 and 9 approach their low deadpoint. vThese ports may be closed by a piston 18 which moves Whilecompressing a spring 19 under the effect of the compressed air acting onits rear surface 20.

Serial No. 466,144.

When the` pressure of the compressed air reaches the xed limit (which isdetermined by the compression of the spring 19) the piston .18obturatesthe ports 16, 17, and the admission ceases and is resumed as soon as thepressure has decreased in the piping. At this instant the spring 19pushes back le pi'ston 18 which again uncovers the ports The exhaust ofthe compressed air is effected through the conduits 21 `provided in thecasing and in a valve box 22. F our exhaust valves such as 23communicate through a common chamber 24 With the outlet pipe for thecompressed air. l

The compressor above described is arranged so that it can be adapted toany motor, single or tandem with the magneto, the lighting dynamo or anyother accessory member. It could be comprised in the same casting Withthe block of the lcylinders of the car motor, insteadk of being anindependent member as in the example illustrated.

What I claim as my invention and desire to secure by Letters Patent ofthe United States is cars and the like comprising inclined aircompressing cylinders, pistons in said cylinders, connecting rodsconnecting said pistons to said crank shaft, a Worm Wheel on saidcrank-shaft, a `Worm 'gearing With said Worm Wheel, an elastic jointcoupling said Worm to the motor shaft, a chamber in communication withsaid cylinders, a piston valve movable in said chamber, a spring-actingon said piston valve which obturates the air admission ports of saidcylinders When the pressure of the compressed air attains a determinedvalue and valves regulating the delivery of the compressed air. InWitness whereof I have signed` this specification in the presence of twoWitnesses l MARIUS ADENOT.
